15 Claims.

This invention relates to closure constructions, and has for an objectthe provision of a closure construction which represents an improvementover that disclosed in my allowed application Serial No. 314,706, filedOctober 24, 1928, issued April 7, 1931 as Patent 1,799,719.

The closure construction of my aforesaid application comprises a hingedclosure, such as a sash, and a hinged screen so disposed with relationto a window orother opening that the screen is toward the inside withrespect to the closure, permitting the closure to open outwards from itscasement without having to leave the screen also in open position.

The present invention contemplates the adaptation of substantially thesame principle to metal sash and casement constructions, it beingunderstood that the device of the allowed application has been appliedspecifically to other constructions.

A more detailed object is to provide a closure construction in the formof a casement having a closure, such as a'conventional steel frame sashhinged thereupon upon adjustable hinges, permitting the insertion of ascreen frame or an auxiliary sash frame between the casement and thefirst mentioned sash frame, both frames being mounted for pivotalmovement about a common axis in being swung to and from closed position.

Another object is to provide an auxiliary frame as described, which isreceivable between the main sash frame and the casement, and which isadapted to maintain a. plurality of lines of engagement of the closurewith the casement, these lines substantially encircling the opening ofthe casement so as to provide a multiple seal when the closure is inclosed position.

A further object is to provide a novel hinge construction, whereby theadjustment of the main closure necessary for the insertion of theauxiliary frame, is made possible.

A still further object is to provide novel means for mounting the screenor auxiliary frame upon the same hinges as those upon which the mainclosure frame is mounted, this mounting means permitting facile removaland replacement of the screen or auxiliary frame whenever desired, thusfacilitating the operation of washing the pane or panes of glass in theclosure frame.

The invention possesses other objects and advantageous features, some ofwhich, with those enumerated, will be set forth in the followingdescription of the inventions particular embodiments which areillustrated in the drawings ac- 1931, Serial No. 525,534

The conventional construction of steel window casements and sash framesis such that a double weather seal encircling the opening of thecasement is established when the sash frame is moved to closed position,inasmuch as the sash frame makes engagement with the casement in adouble line of contact encircling the opening. The present inventioncontemplates the provision of a novel construction whereby an auxiliaryframe, such as a screen frame or the frame of a stormsash, may be addedwithout destroying this double seal. The auxiliary frame, furthermore,is disposed upon the inside with respect to the window construction,thereby permitting the main frame to be left open, without requiringthat the auxiliary frame also be left open, as is the case inconventional screened closure constructions where the screen is hungexteriorly with respect to the closure.

The preferred embodiment of my invention has been illustrated as beingcooperatively associated with a steel window casement 11, whichcomprises a substantially Z-shaped strip 12 substantially encircling thewindow opening 13. Inasmuch as the casement illustrated is double, i. e.is provided with twowindowopenings 13,, the central stile 14 of theeasement 11 is common to both openings 13, and therefore, instead ofbeing Z-shaped in cross sectional configuration, is substantially T or Ltheir respective planessubstantially coincides with the distance;between the planes of the base flange 16 and the bead 17; of thecasement 1-1. The

present invention contemplates the provision of hinges 27 for'the'closure frame 21,,of such a nature that they may be, adjusted subsequentto installation, thereby permitting mounting the screen or storm sash atany time that may be desired after completion of: the'building in whichthe casement 11- isgmounted These hinges 27', however, are of, such a.nature that. when the screen or storm sash frame is not present theclosure.- frame when closed establishes a double storm proof seal withthe easement 11. This isaccomplished asa result of the fact that thebase flange 24, of the closure frame 21. engages the base flange 116 ofthe casement 11- at the same time that engagement takes: place betweenthe outer flange 26 of the closure frame 21 and: the outer surface ofthe bead 117' which extends outwards with re:-

Tspect to the base flange 16.

The closure frame; 21. is: illustrated as being provided with a pane 2,8of, glass, with the-result that light may be-admitted through theassociated opening-1'3 when theframe 21 isswungclosed, but

' aircurrents excluded.

The auxiliary frame 31 is preferably in the form of a channel 32-opening outwardswithin, which a smaller channel 33. isreceivable, theoutside width of the smaller channel 33, beinggsufliciently smallerthan:the; insidewidth of the channel 32'to permit 31 is, in the presentvmodification,v designed as a screen frame, it is entirely within thescope of the present invention to substitute a second pane of glass orother suitable material for the screen 36, under which circumstances theauxiliary frame 31 would support a storm sash instead Ifof a screen.

The outer edge of the channel 32 of the auxiliary frame 31 is continuedin the form-of a substantially Z-shaped' flange 38, the base 39 of whichis adapted to be received between the base -Tflange 16 of the casement.121; and. the flange 24 It should.

of the closure frame 21, and the outer flange 41 of which is adapted tobe received between the outer flange 26 of the frame 21 and the bead 17of the casement 11. Hence, the imposition of the screen frame 31 betweenthe closure frame 21 and the casement 11 necessitates adjustment of theclosure frame 21 in such a manner that it is moved outwards a. distancesubstantially equal to the thickness of the extension 38 of the channel32. The hinges 27, by means of which the closure frame 21 is mounted,are provided with means for effecting this adjustment.

Each of these hinges 27 comprises a casement leaf 42 secured to theouter face of the casement 1 1 and extending outwards preferablyangularly with respect thereto. The pintle pins 43, which are rigid withthe outer ends of these leaves 42, are in axial alinement, permittingthe leaves. 44 which are secured to the sash frame 21 to be mountedthereupon for pivotal movement, whereby the sash frame 21 can optionallybemoved-:toopen or closed position with respect to the casement 11.Instead of being journaled accurately upon the pins 43, however, thesash leaves 44 are provided with substantially ovalshaped holes 46materially larger than the cross sectional area of the pintle pins 43,and within each of these-holes 46a complementarily shaped bushing 47 isreceived. Each. bushing is provided' with a. hole 43, within which oneof the pintle pins 43- fits accurately, but instead of being midwaybetween the ends of the major axis of the associated oval-shaped bushing47 the hole 48 is nearer one end than the other of the bushing;Moreover, the major axis of the hole 46 in each of the sash leaves 44extends substantially perpendicularly with respect tothe plane of thesash, with the: result that by reversing the bushings 47 within theholes 46 in their respective leaves 44 the effective length of thoseleaves may be varied. Thus, it may be seen that if" the closureconstructionv is installed, without the auxiliary frame 31, the bushings47 should be turned so that theholes 48 therein are adjacent their outerends, thereby increasing: the effective length of the sash leaves 44 andcausing the sash frame 21 to establish the doule' weather seal, with thecasement 11,- as hereinabove; described. However, when it is desired tomount the auxiliary frame 31, the bushings 47. should be reversed,positioning. the holes 48 adjacent their inner ends, thus decreasing theeffective length of the leaves 44 and: spacing the sash: frame 21, whenclosed, outwards from the casement, 1.1 a, distance equal to twice theeccentricity of the holes. 48 with respect to the center of thema-joraxes of their respective bushings 4.7.

The auxiliary frame 31 associated with each of the window openings 13 ismounted for pivotal movement about the same axis as that about which theassociated closure frame 21 is mounted. This is accomplished by means ofthe extended. pintle pins 43, permitting each of. the pintle pins 43" topivotally receive a leaf 51 connected to the'associated auxiliary frame31. Instead of being rigidly attached to the auxiliary frame 31,however, the hinge leaves 51 carried by each. pair of alined pintle pins43' is connected to a standard or bracket 52 which is disposedvertically within the space 53 between the webs 18 and. 23 of thecasement 11 and the closure frame 21- at the hinged side of the closureframe. Means are provided for removably mounting the auxiliary frame 31upon the vertically extending portion54. of the bracket 52. Preferably,this is accomplished by means of a plurality of pins 56 which extendfrom a face of the vertical portion 54, each pin having a head 5'7. Theflange 38 is provided with a similar number of vertically elongatedholes, each of which is of keyhole shape, inasmuch as the lower end islarge enough to receive the head 5'7 of one of the pins 56 therethrough,whereas the upper end of the hole is slightly larger than the shank ofthe pin 56 but smaller than the head 57. This permits the auxiliaryframe 31 to be mounted upon the bracket 52 by engaging the holes in itsflange 38 upon the pins 56 of the associatedbracket 52, with the frame31 in slightly elevated position, and then' permitting the frame 31 todrop until the pins 56 are seated within the upper smaller ends of the'holes, the parts being so proportioned and arranged that when the frame31 drops in this manher it comes accurately into proper position withrespect to the easement 11 and closure frame 21. Each of the leaves 51is in reality a.

lateral extension of the vertical portion 54 of the associated bracket52. However, inasmuch as the conventional arrangement of hinges whereonmetal sash are mounted positions the pintle pins 43 extending towardeach other from their associated hinge leaves, one of the arms 51 ismade up of two sections 58 and 59, releasably united by means of aplurality of screws 61 or their equivalent. This permits mounting thebracket 52 for pivotal movement upon the same hinges as those upon whichthe closure frame 21 is mounted, by disassembling the two-piece arm orhinge leaf 51, seating the eyes 62 which are provided at the outer endsof the arms 51 upon their respective pintle pins 43, and thenreassembling the sections 58 and 59 of the arm 51.

In order to accommodate the arms 51 of each bracket 52, the flange 26 ofthe closure frame 21 is provided with a slot 63 in the hinged edge ofthe frame 21 in position to permit each arm 51 to extend therethroughinto the vertical space 53. The outermost flange 41 of the Z-shapedstrip or flange 88 of the auxiliary frame 31 is also provided with aslot in registry with each of the slots 63 for the reception ofthe'associated arm 51.

Figs. 6, Tand 8 shows a slightly modified form of hinge construction,whereby the same adjustment of the closure frame 21 may be attained. Thepintle pin 66 extends through a closely fitting hole 6'7 in-the casementleaf 68, and preferably a washer 69 of friction material is interposedbetween the head '71 of the pin 66 and the leaf 68. Another washer '72of friction material is interposed between the uppersurface of thecasement leaf 68 and the lower surface of the closure frame leaf '73. Anelongated hole '74 is provided in the leaf '73, through which the pin 66extends, and means are provided for retaining the pin 66 in the outerend of the elongated hole '74, this means being in the form of a metalwasher '76 having lugs or cars '77 which are bent down in engagementwith the side edges of the leaf '73 to insure turning of the washer '76with the leaf '73.

Another lug'78 is provided upon that edge of the washer '76 which isremote from the window structure, and by bending this lug '78 downwardsacross the outer end of the leaf '73 when the leaf '73 '1 has beenpulled inwards so as to dispose the pin 66 in the outer end of the holeas illustrated upon Fig. 9, the pin 66 may be retained in this end ofthe hole. This is the position occupied by the leaf '73 and the lug '78when the auxiliary frame 31 is not mounted upon the window construction,

inasmuch as this arrangement of the parts will result in holding theclosure frame 21 rigidly against the easement 11, so as to establish thedouble weather seal encircling the associated opening 13. When it isdesired to mount the auxiliary frame 31, the lug '78 may be bentupwards, whereupon the closure frame 21 may be moved out wards adistance equal to the elongation of the hole '74, thus permitting thereception of the flanges 39' and 110f the auxiliary frame 31 be tweenthe casement 11 and the closure frame 21.

Another washer '79 of friction material encircles the pin 66 above themetal washer '76, and a nut 81 is threaded onto the pin 66 above thewasher '79, so as to cause the parts to press against the frictionwashers with sufficient pressure to establish the desired amount offriction, whereby the closure frame 21 will be retained in adjustedposition against the action of wind, and the like. a

' Another washer 82 of friction material encircles the extended portion83 of the pin 66 above the nut 81, and the leaf 84, which is connectedto the auxiliary frame 31, is removably receivable upon the extension 83of the pin 66, as clearly shown upon Figs. 6, '7 and 8.

Any suitable latch means may be provided for releasably securing theclosure frame 21 and/or the auxiliary frame 31 in closed position.Preferably, this latch construction, which is indicated in its entiretyat 86, is of the type disclosed in my aforesaid copending application,and comprises a shank 8'7 pivotally mounted upon the screen frame 31,and carries a pair of engaging detents 88 and 89, The former of thesedetents, 88, is adapted to be received within a slot 91 in the stile 14which separates the two window openings 13, whereas the second detent 89is adapted to engage an ear 92 which is rigid with the closure frame 21,thereby locking the screen frame 31 and close frame 21 together. Theinner end of the shank 8'7 is provided with a handle 93, whereby thelatch 86 may be operated.

It is to be understood that the details of the invention as hereindisclosed, are subject to alteration within the spirit or scope of theap pended claims.
